I use the "bootloader" version of this board. It's great! I can program the board with the USB connector on the top side. On the same connector I can connect the computer with the same cable and make a connection as an rs232 and send/receive date from the computer. It's working with 921kB. Can I use...

I need a litle help to solve this IRQ Problem....

Hi Ben
I dont use a quarz
I did the test like in the wiki..

I have a problem with a pic24ep256gp206.
I chosed 70 000 000 Hz for the delay and IRQ.
In the progam I made a delay of 1 Second but the delay is about 10 seconds.
Can I put an C-Code to config it to 70Mhz?

Hi Ben

I wrote a small program for the IRQ
It's working if I disable the part.
What can be the problem? In the attachment is the small program.

Hi Ben

I changed and in the Box now I it's 0s.
something changed with the IRQ.
But I can put only one command in the IRQ-macro. If it's more than one the programm is not running anymore

Hi Ben First I would like to mention that the chipkit WI-Fireboard is very nicely integrated into Flowcode. Thank you very much. But I have a little problem with the IRQ ant the chipkit Wi-Fire I tried to change from 01 to 0s but in the bootlaoder is alway this 01. I can not even click in the box wi...

Hi Ben

I have now FC7.2 and I have the Problem with the IRQ. The program stop if I use an IRQ

I have to convert an integer to a string. The integer has a value from 1 to 12.

The string needs always 2 numbers

result_string = ToString$ (1) // the result_string is "1" but I need "01"

I instaled today FC7.2 but it's the same. FC7.2 is crashing to. So I still use my win10 computer for FC7 and wait for 7.3....

Hi Ben

I found the "Problem". I removed the Initial Value (0,1,0x2,0x03,'A','b',"Hello") from the EEprom-properties and now there is no 40seconds waiting time for programing anymore.

Hi Ben Thank You. I saw it in the ICD-File. I have to enable the watchdog an run a whileloop for ever. something else I have. I used the eeprom in the chip.The bad side effect is, that if I download the program to the chip, it's takes 40seconds time to write EEdatamemory. But I use only 3Byte in the...

Hi Ben Is there a way to reset the cpu like an another compiler? ///////////////////////////////////////////////////////////////// Control // Control Functions: RESET_CPU(), SLEEP(), RESTART_CAUSE() // Prototypes: _bif int8 restart_cause(void); _bif void reset_cpu(void); _bif void sleep(void); _bif ...

Hi Ben Now I have to begin with the 10channel recorder. For this project I try to use the chipkit wi-fire with the PIC32MZ2048. The board include a micro-SDcard connector. I tested the card but it's not fast enough. Is there a possibility to to increase the speed. This Pic has much more ram. Maybe w...

Thanke You both

With this help I did a C Code...
It's small in the mainpart and the big part is easy to copy-paste.
FC7 is really nice to use

Hi
How to use a switch, but the case is a range ( not a fix number )
like 1-500,501-1000,1001-1500

Hi Ben
perfect! Thank You. And here a sinus 200Hz Signal sampled with 2kHz and saved as data like a wavefile on a micro-sdcard and open with Audacity (import raw).

Hi Ben Thank You for the special FAT.It's working faster and I can use my 2channel recorder. I have now a another small problem to write in a corect way the data to the wave file. before with CCS I dit it like this to convert the 10Bit uint from the AD-converter to little Endian signed16Bit. But how...

Hi Ben
"We have a new version of Flowcode"
That nice to hear. Is this FC8 or FC7.2 ? And when can I have it?
Is there a newsletter about FC or general?

Hi Ben Thank for the FAT. I'll test that. And I hope for the 2channel 2kHz recorder with this older PIC will work. Soon I start to go on with a 10channel 2Khz recorder. I saw microchip has now ARM® Cortex® from Atmel As if there are faster (300Mega) and need less power... They have a HSMCI port (Hig...

Yes it's every 64times that is going long. Unfortunately I need the FAT. A ringbuffer is not so practical, the 18LF6722 has "only" 3936 Bytes RAM. I hope it's possible to do some improvement of the speed. I think we are close that to the 2Khz goes .... Anyway the FAT System from you is very comforta...

Hi Ben At first, the Fat from FC is realy nice to use and is working fine. It's create file by file on a card. I have PIC 18LF6722. It's working on 32Mhz. There is a SD Card on the board. The card is working with clock/4 I used the Blockwrite (write file sector). The goal is to sample 2Channel 16Bit...

Hi Ben I have a PIC 18LF6722. I like to config like in the Manual on 40MHz (or 32Mhz). I can not make it faster than 8Mhz. I can config in C-code the two Register but not the CONFIG1H FC7 can not found it. Can I define it by my self if I know the addres (300001h)? OSCCON = 0x70;// 8Mega OSCTUNE = 0x...

Oh Thank you Ben
I have a wish more ....
Write to the first block before I close the file. I need it to write in the fileheader
- how many block there is in the recorded file(data)
-start and stop time

Hi Ben
Is it possible to have longer File name as the 8.3?
