Hi, I run ADC1 with DMA on my STM32F303RE with 72MHz clock. I take the number of samples flowing into the circular buffer per timeunit. I calculate a sample freq. of 1.305 Megasamples per second Ms/s. When I look at the sampled known signal I calcu...
Hello,I recently replaced an existing STM32F767 MCU with a new STM32H753 MCU in my project that involves SPI communication with an FPGA using 16-bit data frames. After the replacement, I encountered issues with SPI read/write timing and overall commu...
Split from: Power Supply for STM32F030 Cortex TSSOP20 VDDA and VDD pin; specifically this post.@TDK wrote:that satisfies the condition. But only the "VDDA >= VDD" condition - it doesn't satisfy the "VDDA must be first" condition. As noted, I suspect ...
Please i need help. The datasheet, says the VDDA voltage level must be always greater or equal to the VDD voltage leveland must be provided first. My qustion is: will my circuit work, if I tie the VDDA and VDD together, to be powered by the same LDO...
Hello,I am learning bare metal programming for STM32F446RE and am trying to write a simple transmit driver for USART2. I managed to do it but my only problem is when I use HSI 16Mhz clock speed (or anything lower) I get a weird first character. When ...
Dear STM experts: I am using the STM32G473RET6 chip for classic mode communication debugging in FDCAN, but there is a phenomenon where I cannot send information. In FDCAN-PSR, I can see an error of LEC being 5. After removing the CAN chip (SN65HV...
Hello guys,I have a stm32G474RET board. I am using tim1 in PWM input mode and i want to update on the fly the hrtimA period and compare values using DMA. This is the code i have written: // Addresses for HRTIM registers (Timer A) destPER = (uint16...
We have a batch of custom boards using the STM32H725IGK3 and have experienced several failures getting started with them as the SWD interface appears to be fried. Initially we thought just bad luck with the first couple (inexperienced engineers or ?)...
Testing a board with STM32U5A5. VDD is 3.3VI have configured one GPIO as input with an external pullup to 3.3V through a 470k ohm resistor.The input reads high, but when I measure the input with a scope, I read 2.2V on the input, which is below 0.7VD...
Hello ST Community teamThe pin F11 on the TFBGA216 figure (figure 4 of the AN4660) should be VDD and not VSS according to the products datasheets (for the STM32F469N and STM32F769Nx6). That should be rectified on the next doc revision. Best Regards.I...
