Hi

Not been able to have a look yet, but hope to tonight.

Hi If you download the file Jorgen kindly shared in a previous post https://www.matrixtsl.com/mmforums/viewtopic.php?p=100454#p100454 and then change the target to your 877A you will be well on the way. You will need to reassign a couple of pins (but not many). I've no access to hardware at present ...

Hi

If you post your chart we can have a look.

Regards

Hi Have you tried to convert it yourself? Flowcode is chip independent so it is usually quite easy to port from one device to another, assuming the new target is capable (RAM/ROM/Ports/Peripherals/Speed etc). If you go to Build and select the 877A as your new target you may get warnings about port p...

Hi

Sorry to hear you are unwell. I hope you get better soon..

Hi Have a look at the attached file Echo_Test Echo_Test.fcfx In this chart we still flash the LED in the Main loop, but we also use the UART and an Interrupt. The purpose of this chart is for you to connect your PC to the chip as before (Tx-Rx / Rx-Tx) and then using Terminal, whatever you type in T...

Hi Excellent :) Take note of how you connected everything together, connections, settings, everything. Do note that although you are using Terminal Com Port 3 just now, this may change when you next insert the adapter, or use another USB port on your PC. Next we can look at sending from your PC to t...

Hi Looking at your screenshot you are doing well. This is exactly as I'd expect as you are sending from chip and it is being received by the Terminal program. All is good :) :) Next I'd suggest you modify the SendString command to instead of sending "U" it sends "U\r\n" You should now get U U U etc ...

Hi I can well understand your frustrations but you are very close to getting things to work to don't give up. Don't try and jump in at the deep end straight away. Instead work through each step. I am quite sure from your previous tests that the esp8266 module is working and your traces showed that t...

Hi Windows automatically found and installed drivers on W7 / 8.1 / 10 and 11. Rollback could be a good idea. I'm not sure why you wish to focus on obtaining the Firmware version on an LCD as there is a LOT of information to capture and display. I see zero need for this as you have already confirmed ...

Hi I'm not sure I understand what you mean by deleting the program but driver is still there. Were you attempting to delete the driver? It is better to not insert both adapters at the same time until you are sure both are good and can differentiate between them. Many times Windows get hung up with t...

Hi I would double check you are actually on Com1. Clicking the arrow beside will give you all options. Once you are sure you have selected the correct Com, click on Connect. Then whatever you type in Area 3 should appear in Area 1. If you type in area 2 it won't be sent until you click the "send" bu...

Hi Did you do a loop test? Plug your adapter in to your PC loop the Tx to Rx Open Terminal Select correct Com Port Connect Type in anything and you should see it appear on your screen. If not then try another Com port until you find it. Once you can do the above, connect the Rx pin to your 328P Rega...

Hi That link shows an adapter that only has +5v available as a power option (to power whatever). Many are out there that have both 5v and 3.3v. It isn't too much of a problem as you can always drop the voltage using a divider or simply not connect it and power say your module from another source. If...

Hi In the long term, it would be better for you if you had a USB-TTL adapter similar to this https://www.amazon.co.uk/PL2303-Converter-Adapter-Module-Adaptor/dp/B0D2VJNMTK/ref=sr_1_10?crid=199XBQS7WKQ1Z&dib=eyJ2IjoiMSJ9.48AB82uEGRRBV5KdAiW4Rn3VQ5ko8ww_ZWu1IayBLo0bveX8Vx0fovJyvybG2sXjD3iIMHmYSOW5H3j3...

Hi If you re-read Martin's tests, they suggest that the Mega8 is not a suitable chip to use for anything other than basic UART comms, which prohibits using the esp component. It is a bit like wanting to sail across the Atlantic but you only have very small rubber dinghy...... :) Flowcode is target i...

Hi It's good news that you now have the chip working as expected, and yes, the test diagrams I sent work for all chips, not just the Mega8. A big thanks to Martin for taking the trouble to set up and test with a Mega8 and establishing the limitations of using it. The tests were to help establish wha...

Hi Martin Thanks for doing those tests which really are helpful. I hadn't even started to think on the "receive", waiting until it could transmit, so your finding are very useful especially as I have no experience with this chip. I too think given all of the above that his best course of action in t...

Hi That's interesting. I did find a few issues with the component which I documented in other posts (new and old forum). One being when issuing ClientConnect the component returns a 0 even if successfully connected. This is attributed to espressif / clones / whomever changing firmware after the comp...

Thanks Martin You have just proved that the FC esp8266 component itself works with the ATMEGA8 and there is nothing inherently wrong in the FC / ATMEGA8 combination. If gilanetugila can't get his ATMEGA8 to output anything useful using the esp8266 component without also having the UART component too...

Hi

Now you are using the 328P remove the UART component and all references to it, just leaving the esp component.

Connect your scope to the 328P chip, leave the esp completely disconnected and run the flash test / sendstring "U" test.

Regards

Hi Okay Dokay, my mistake regarding the USB-TTL module. Have a look at the attached. It doesn't show all connections necessary but does provide an outline of what we need to do. Test Connections.pdf First diagram is just microcontroller to esp8266 module Test-1 In this setup you can run your termina...

Hi Looking at your schematic, I think the esp "adapter" will be a cause of issues as that has other components on it too. Only use that when you are connecting the esp8266 to your PC as you did in earlier posts. Don't have it connected at all to your esp8266 when your chip is trying to communicate w...

Hi When composing and sending a string \r = Carriage Return (CR) \n = New Line or Line Feed (LF) These will be included in what the component sends out. Your traces show pulses in excess of 4S (low) and 7S (high) so something is clearly wrong. You mentioned earlier that you had a 328P chip. Perhaps ...

Hi Using an UNO R3 (uses a 328P chip) I connected up at 115200 baud. No issue. 115200.jpg Zoom in 115200 zoom.jpg I then changed the flowchart to instead of sending a "U" it issued the GetFirmware command (AT+GMR CR LF). No issue there. However do note that as I did not have an esp8266 module connec...
