Re: Rebooting to DFU bootloader in F4 and others.

No, I'm still fighting with Eclipse debugging for F4 (as presented in another topic).

Re: libmaple version of MCO output

I think Victor did a good job, we should include it to rcc.c . Just as side note, the inderkluuk's code for OV7670 originally uses MCO output (PLL/2): https://github.com/indrekluuk/LiveOV7670_stm32-arduino/blob/master/src/LiveOV7670stm32/src/camera/base/CameraOV7670.h#L81 I changed it in my version ...

Re: Rebooting to DFU bootloader in F4 and others.

Here is the code I was testing: #include <Arduino.h> void RCC_DeInit() { /* Set HSION bit */ RCC->CR |= (RCC_CR_HSION | RCC_CR_HSITRIM_4); /* Reset CFGR register */ RCC->CFGR = 0; /* Reset HSEON, CSSON, PLLON, PLLI2S */ RCC->CR &= ~(RCC_CR_HSEON | RCC_CR_CSSON | RCC_CR_PLLON| RCC_CR_PLLI2SON); /* Re...

Re: [POLL (Open)] Blocking behaviour of Serial.USB during TX

I'm with Martin this time.
For applications where high Tx throughput is needed, it must be granted that the host is capable of that high speed.
Otherwise one should be able to select the desired behavior, blocking or not.

Re: Invalid stack in RAM when debugging F4 board with STLink in Eclipse

Yes, that was my intention.
And it did not work, that is why i tried to debug, but debugging is not working for some reason...

Re: [STM32GENERIC/HAL] SerialUSB TX/RX speed problem

Pito, very interesting.
The libmaple F4 USB CDC is St SPL based.
Can you please test libmaple F1?

Re: Proposal for moderators to rename threads etc

Before deleting them we should maybe extract the solution to the particular problem, and add it to a wiki or howto, if not already there.

Re: OV7670, Generic STM32F103RC and ILI9341 display

If you are using the older ILI9341 version, well, you break one basic rule for pixel reading because you will toggle CS (done within the function writecommand()). My new version with reworked CS and DC pin toggling will do it right. When I get back home (in couple of days) I will test and generate f...

Re: What happened to gpio_write_bit and others?

Originally, the pin map already included the ordered pins from PA0 till PG15, so I though the bit information is superfluous. Then I added the pin map to the FLASH and I think it made a difference on the size whether this bit info was included or not in the pin map table. We could re-add the missing...
