I have some troubles to activate the HID on STM32F103C8T6 board.
Thats my test program:
Code: Select all
program MyProject;
{ Declarations section }
var cnt, nread : byte;
var readbuff : array[64] of byte;
var writebuff : array[64] of byte;
counter : dword;
begin
GPIO_Digital_Output(@GPIOb_BASE, _GPIO_PINMASK_0);
GPIO_Digital_Output(@GPIOb_BASE, _GPIO_PINMASK_1);
GPIOb_ODR.b0 := 0; // LED1
GPIOb_ODR.b1 := 0; // LED2
counter := 0;
GPIOb_ODR.b0 := 1;
HID_Enable(@readbuff,@writebuff);
while TRUE do
begin
GPIOb_ODR.b1 := 1;
USB_Polling_Proc();
nread := HID_Read();
GPIOb_ODR.b1 := 0;
if (nread <> 0) then
begin
for cnt:=0 to 63 do
writebuff[cnt]:=readbuff[cnt];
HID_Write(@writebuff,64);
end ;
counter := counter +1;
GPIOb_ODR.b0 := counter.b16;
end;
end.
The program stopps allways at USB_Polling_Proc(); or HID_Read();
I would like to init the USB Module with GPIO_Alternate_Function_Enable but i can not find the correct module in the list.

Have somebody tried this with the same CPU?
Thanks in advance for any answers.
