On STM32F407V-Disc the divisions don't work out for an 192KHz Timer trigger for the ADC, so sampling runs a bit slower or faster, the problem is that the Cirrus DAC audio chip cannot be set to match the sample rate, so I get buffer sync drift, audio ...
I have as simple MENU where I am switching with rotating of rotary encoder between items. If I choose item which I want I can press the button and it open subitem for the item. in open subitem I have stopped rotating of encoder. Because if I was in s...
We want to use external 16 bit SDRAM for heap and stack. The SDRAM is configured with byte enable and MPU. I tried to map the memory to 0xC0000000 and 0x60000000, but it doesn't matter. Also the configuration of MPU with MPU_TEX_LEVEL0 or MPU_TEX_LEV...
I tried the same code on both microcontrollers, but STM32F103RET6 freezes with NVIC_SystemReset(); Can you help me please?
Edge-triggered interrupts had been used by us to identify various system states. However, it appears that the interrupts are now sometime erroneous and cause an undesirable state change. This led us to search for implementations where level-triggered...
Having some trouble with reading ADC channels on this unit only when using multiple channels. I have no problem using a single channel, but as soon as I expand it to two, or more, my readings are just garbage.Code for working single channel: hadc1....
Hello team am Receving 16bit ADC conversion data to DMA in STM32H745i Disco in CubeIDE software. Here DMA interrupt is generating by default in software (i am disabled the interrupt in programming after that program counter is out of control) I dont ...
I use FDCAN in STM32H730 for communication over CAN-FD.At the moment it works with 500kBit/2000kBit without TxDelayCompensation. But we want to communicate with 1000kBit/4000kBit too. Therefore I want to enable TxDelayCompensation.I'm not sure how I ...
RTC SubSecond does not generate an interrupt with an STM32C031.Interrupt works perfectly on calendar type alarms.I work in LSE at 32768KHz, divider 127 and 255 RTC_TimeTypeDef sTime = {0}; RTC_DateTypeDef sDate = {0}; RTC_AlarmTypeDef sAlarm = {0};...
