Do you have a DVM to check the power supply voltage on the Click module?
Also check the RS232 Tx output voltage.
Presumably the Click RS232 is connected to COM1 PC port?

Yes, it's going to take some work (new toolchain, CAL etc)
Raspberry Pi modules to date use a Broadcom device and run an operating system (Linux) the Pico does not.
But it's a very interesting device

In that case you might as well use high value resistors. Two the same will limit the maximum ADC voltage to 4.5v. The ADC input current draw when sampling will cause the ADC voltage to drop. But in this scenario you could calibrate the ADC readings for your own purposes. That is, determine the ADC v...

Hi Bob, 68k resistors would not provide a low enough source impedance. Do you need to measure the voltage accurately, or is it just a "battery low" indicator? Is this for a "maker" project, or a product designed for quantity production? This will help determine the best way to go with this, as there...

The datasheet gives a sampling current of about 250uA
which as you say will equate to a parallel resistor, of ~20K
So depends what kind of accuracy you require

Hi,

If you are using...
BL0032 E-blocks2 dsPIC Programmer
BL0101 E-blocks2 Click Adaptor board
Then the port pin mapping is as follows...

Reset - 7
CS - 2
SCL - 5
SDA - 3
DC - 6

For Port D/G this would map as...

Reset - G9
CS - D10
SCL - G7
SDA - D11
DC - G8

The compile error is because you had a Timer component in your project, but did not have any of its functions on your flowchart. L'erreur de compilation est due au fait que vous aviez un composant Timer dans votre projet, mais que vous n'aviez aucune de ses fonctions sur votre diagramme. Timer.png T...

There are no spare inputs.
But you could link across to either (UART0 RX) Port E1, or (UART1 RX) Port E3
Assuming you don't require both UARTs
These are available if you remove the UART selection header link ...

Which version of MIAC are you using?

Hi,
Sorry for the omission.
It's the same for V3 MIACs, dsPIC etc.
Thanks
Leigh

Similar to Ben and Steve, a two wire RS485 or single wire-or'd (open collector driver) if data rates are slow. As a very simple protocol .. If you connect to an 8 bit UART you have 256 codes or addresses for the slaves If you reserve 2 codes for on/off you could then use the master to poll each slav...

The transceiver is a SN65HVD10DR which has built in ESD Protection,
but external extra TVS sounds like a good idea in your application

Hi,
No, there is no internal termination resistor.
Or pullup/pulldown
Regards
Leigh

Hi Stefan, I've now fixed the SSID reading, I will ask Ben to push this out on the update system. Please note that we currently limit the maximum SSID count to 8 (to conserve memory), but we can change this in the CAL if it becomes necessary. Also the SSID information is an array so starts at 0, not...

Please try the attached update file, and restart Flowcode, to go into ...
C:\ProgramData\MatrixTSL\FlowcodeV8\FCD\ARM

Please note that STM hardware I2C will only work in "transaction" mode
Please use the I2C CAL component Transaction..() API

gLCD_SSD1306_i2c
I2C Channel 1
SDA PORTA.5
SCL PORTA.15

Could you please try the attached updated file,
to go into directory ...
C:\ProgramData\MatrixTSL\FlowcodeV8\CAL\STARM
Thanks

Could you post your project fcfx file?

Thanks for the spot.
Please try the attached, to go into ...
C:\ProgramData\MatrixTSL\FlowcodeV8\CAL\PIC32BIT

Looks like the updated PIC CAL file is now in the update system OK.
Can you check you are up to date?
If you still have an error could you please post a sample program demonstrating the issue that you have?
Thanks

I think the issue is that you will need to use the Software I2C mode with this Gyro component.

Might be worth starting with reading the temperature instead, that should give a more stable output.
Also, there is a "console debugger" component for Raspberry Pi, where you can print out values to a console display.
Just search for debug components to find it.

Hi Jorgen,
Thanks for your update.

Could you please try just printing something simple on the display, such as "1234567".
then take a photo in orientation 0 and 1
(I don't have one of these displays)

Hopefully we will get the FCDX changes to the auto-update system soon.

Thanks
Leigh

Hi Jorgen,

If a previous version of the gLCD component worked OK for you,
could you try rolling back to that version via the update system?
let us know how that goes and it will help us to track down the issue ...

Problems with the ILI9341 gLCD?
Can you give more details? Perhaps a photo?
Can you check your SPI settings?
