I am working on STM32H753 microcontroller. I want to receive string using UART interrupt and send the same string back on UART. The IDE is keil uvision 5. The problem I am facing is that when I first program the MCU UART is working fine and I am rece...
When I increase the value of FOSR and IOSR,Iam not getting the proper values output from the dfsdm filter it keeps varying and is not also proper HAL_DFSDM_FILTERREGULARSTARTDMA(&hdfsdm1_filter0) How to keep the values of FOSR and IOSR?
Hi guys, I'm starting from a bare STM32G070KB, and cannot for the life of me get it to connect.I had this problem with an STM32G071CB but was able to solve it. The problem I was having was that I couldn't get an ST-Link to read the chip on a breadboa...
STM32F050C4T6A I want to use as a drop in replacement since I cannot find stock in the STM32F030C8T6 When I installed it in my board I use two I2C ports and they both work but the manual says there is only 1 I2C port. Am I ok to use this chip going f...
Hi,I am trying to perform continuous ADC conversions from a microphone using DMA, save that data to a large buffer, and then transmit that data using Uart (DMA). I have successfully setup the ADC to perform the DMA conversions along with saving them...
Hi, I have the problem that I get an endless slave Clockstretching.STM32F072 I2C configured with CubeMX, Primary slave adress $32If I fire a Tx frame from a master with for example:HAL_I2C_Master_Transmit(&hi2c1, 0x64, buf, 1, HAL_MAX_DELAY);The cloc...
Hello,I am using GCC and eclipse CDT. I need to execute an external interrupt very fast (every 4µs). There is not a lot to do in there but I use about 2.5µs of time in the interrupthandler. I tryied to put the handler in to ram wich gave me the reloc...
We switch several times the µC into Standby Mode and the current is as described in the specification.But sometimes over the Vdda Pin the current is 1mA. We switch adc/dac vrefint etc off. No BOR in use.We checked each Ports, but the current is comi...
Hi, i got a fan failure project . For that i need to select 2 adc channels in DMA mode for rms calculation , and 2 digital input for my powerfactor reading . here i am using AC (230Vac) and DC (5v) supply both .I select two timers with 100khz in...
Hello everyone! I am trying to debug some code but there are some flags in flash that keep getting set when I exit debug and it enters run mode (or when I power up the sensor. Basically, anytime it gets a chance to run before I can get it in debug ...
