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};...
Hi everybody! I keep trying to out a PWM signal, using TIM1 ch1. CC do trigger fine, but the output pin doesn't change. Please help!void TIMER_init(void){ //PA8 - CH1 GPIOA->MODER &= ~((3 << GPIO_MODER_MODE8_Pos) + (3 << GPIO_MODER_MODE9_Pos)); //Sw...
I'm having trouble with my STM32h757 processor. I'm trying to sample 2000 samples using ADC3+DMA1/DMA2/BDMA, but it's not working as expected. I set up the ADC to work in continuous mode and the DMA to work in circular mode with the address increment...
Hi guys,I'm "trying" to establish a STABLE communication between USB FX2LP sync slaveFIFO and STM32 MCU, in particular with the STM32L412KB for now.I need a stable data transfer from STM32 DMA-GPIO to FX2LP slaveFIFO with DMA clock 3MHz (later higher...
