Hi all, I'm trying to have the ADC sampling rate controlled by a timer (TIM9 in this case) and when 8 samples are acquired, DMA will fire a transfer complete interrupt. So far I'm able to get the ISR to fire one time but never again. In main I set up...
Hi,I want to compute the moving average of an IR sensor and set the brightness of an LED and im taking input values from read and I have set up an a timer interrupt which gets triggered every 100ms, and with this trigger I'm saving the read values in...
HiI am new at stm32 and build my can bus code i can receive and loop std id message between can1 and can 2 without problems. But when i send extended ID FIFO didn't receive them so didn't loop to another cansetup stm32f105transreceiver actual TJA1055...
Using STM32 HAL and a STM32H7 (I know some dissuade the usage of this). I have created 2 MPU Regions of non cacheable memory .void MPU_Config(void) { MPU_Region_InitTypeDef MPU_InitStruct = { 0 }; /* Disables the MPU */ HAL_MPU_Disable(); /** I...
I am trying read continuously from an external ADC. I want to use DMAMUX to do an SPI read from the ADC via SPI RX (MISO) without interrupting the MCU. I have an external data ready signal that gets low whenever data is ready. I want to use this exte...
Im trying to use ST7920 GLCD with STM32F401RE with I2C connection, im still new with programming so im trying to find a library when using I2C, most videos and libraries i found are for SPI connections.if anyone has a library pls help thank you
hii want to write in AT24C512 with stm32f103c8 i send my code.HAL_I2C_Mem_Write(&hi2c1, 0XA0, 0X11FA,I2C_MEMADD_SIZE_16BIT , &write_data, 1, 100);For example, I want to put the value of write_data on 0x11FA, and I specify the memory address as 16 b...
I have TIM1 clocked at 20MHZ, PSC = 20000 - 1, ARR = 1000 - 1, RCR = 2 -1 .....I have Channel 1 as Output Compare CH1....I have TRGO set to Output Compare (OC1REF). Finally to validate what I hope TRGO is doing (since there is no way to see TRGO dire...
I have experimented with STM32U575Z using FMAC. I run the FMAC doing a convolution (sFmacConfig.Filter = FMAC_FUNC_CONVO_FIR) I run the FMAC in DMA mode. I registerd a HAL_FMAC_OUTPUT_DATA_READY Callback But it is never triggered. According to AN5593...
Hello all...Can someone give me direct answers below...(And please don't refer me to documentation as I have scoured thru it and not solved my questions)I would like some clarity as I have found no documentation to clarify the following:When using co...
