So, we are creating firmware for the STM32F7 that takes pictures and stores them to an SDCard. We have implemented kind of a custom database format which stores a kind of file allocation table in RAM, makes the edits as necessary, and then copies the...
Hi.I'm experiencing a very weird problem with a design, a CAN bus keypad with RGB backlit keys, in which the MCU (STM32F072C8T6) would sometimes overheat to over 150ºC and stop working. This happens some times in first power up of a unit, or after a ...
In the STM32F446xC/E datasheet, DocID027107 Rev 6, footnote under Table 11. Alternate function says:1. The DCMI_VSYNC alternate function on PG9 is only available on silicon revision 3.However, neither DBGMCU_IDCODE description in RM0390 Rev 4, nor ST...
When i m using circular ADC1 DMA and writting data on sd-card,mostly data lost, why?
I have the system clock set as 120Mhz. I used the HAL driver code, HAL_PWR_EnterSLEEPMode, to enter Low power sleep mode. However, when it checks if it's in run mode, it doesn't recognise its actually in run mode. /* If in run mode, first move to...
Hi,Can anyone recommend the best way to generate microseconds delay??and how to generate it??
Hello everyone,We're working in a design with the STM32L151ZE and a power supply of 3V. We're trying to design a connector able to detect when specific resistances are present.I've seen that there are some inputs of the chip that are 5V tolerant, whe...
I wish to use my STM32F429 as a top-notch audio player, driving a good I2S DAC. 192KHx, 24bit, stereo. First of all, can I bypass the internal clock scheme by sending a high quality clock to PC9 (I2S_CKIN) ? From my calculation, I'd need a 49.152Mhz ...
Hey guys,I'm trying to understand STM32F334 high resolution timer (HRTIM) in some details.It says the timer has 217 ps resolution. But how can I achieve that in practice? Let's say I generate PWM signal with 1MHz frequency and 500.00ns pulse width. (...
I have a strange behaviour on a new project with a STM32H743 processor and I am currently stuck.After a successful (HAL returns HAL_OK) erase operation of a flash sector (e.g Sector 4) the blankcheck routine - which worked on all of my other H743 pro...
