I am trying to increase FCLK, and I changed the voltage scaling to VOS0, and configured the PLL1 for 240 MHz (src=HSI (HSIDIV=2), M=2, N=30, P=2), but it did not boot (it freezes when a change the system clock mux to PLL1). I realized when I decrease...
Our product uses an STM32L562VET6Q MCU. We are using an ADC to measure current via a 1ohm resistor. Because the currents are relatively small, I want to use the internal opamp in PGA mode to double the input signal before it is send to the ADC. I ...
Hello,I have a STM32F407 Discovery Board. I am trying out the FatFs_USBDisk demo application. I am running the application from STM32CubeIDE.When I run the application and plug in a USB flash drive, the demo application works as expected. I see the S...
Hi I like to find out How i can start a spi communication with DMA by a timer i tried to search a lot on google for this but didnt found any solution for the SPL and a F4.My Problem is i try to read out a ADC connected to SPI 1 very fast first i trie...
What is the analog bandwidth of the stm32 ADCs in the different series?
Hi All,I have a program that is supposed to transfer data from the integrated ADC on STM32H723 to the D1 RAM. I am using DMA for this, but the problem is that the DMA buffer is limited to 64KB, where I need around 200-250 KB buffer size. Here I am th...
In RM 0481 (STM32H563/H573) Rev 1, on page 444, Figure 48. Clock tree, HSI RC 64 MHz output is written as HSI (hsi_ck), whereas LSI and HSI48 outputs are named as lsi_ker_ck and hsi48_ker_ck. Since there is also a HSIDIV, and it is documented correct...
Hi to all! I connected all channels to possible pins in my ADC. How I can use the HAL functions to select a separate channel and read the value from it? Has anyone faced these issues? I will be grateful for the answer!
Hi, I need to create a system for which it is possible to update the firmware remotely.My system communicates with a serial port (RS422) with a PC, and through this serial I would also like to update the firmware. Obviously without moving the BOOT0 p...
Hello, I'm building a communication between two devices an Arduino Mega 2560 and STM3210E-EVAL. For the communication I need to use RS232. In between the two devices I use the MAX232. I got it working one way where the STM32 sends 1 byte to the Ardui...
