I have read the document RM0433 and AN4235, but the calculation is still a puzzle. For example, if my I2C frequency = 1MHz, I2C clock source frequency = 170MHz, AF=on, DF=off, rise time = 80ns, fail time = 10ns, how do you get the SCLH = 0x10 and SCL...
Hi, I am planning on using STM32H723ZGT6 chip on one of my boards. I got the NUCLEO-H723ZG to measure the 12-bit ADC noise. From the datasheet for STM32H723ZGT6, the max ADC noise should be 5 times the LSB or 4.02mV. (1 LSB = 3.3/4096) I am getting 2...
I think the correct one should be nBOOT0_SEL(bit) = 0 as in previous version.Please verify.
My very smart technicians say they can cut SB16 from +3V3 and they can solder a 3V CR2032 battery socket onto the STM32H747I-DISCO board safely. It is not an easy job they say. I agree.Unfortunately, STM does not provide a battery backup socket for u...
What is the default value of the DBANK bit in STM32G4 MCUs. According to the reference manual, flash memory address 0x1FFF 7800 has that option bit, and the ST production value is 0xFFEF F8AA, which would make DBANK default to 1. Does this mean STM32...
How to create simple non secure only project for STM32N6570-DK on CubeMX to use on board peripherals. by default it creates project with the FBL, secure, non-secure for this device.
Hi,I am using STM32C071CBT6 chip on my custom board. From datasheet, i could see that there are two versions available - GP and N version. Part number section of datasheet mention about 3 more characters after this part no. to identify if it is N ver...
Hello, I am working on the development of a bootloader for the STM32L4S5ZIT6, and I need help to implement a feature where the bootloader is triggered after receiving a user request in the main application (the main app saves a marker in memory). Her...
Hi all! I have been using a F446RE board to communicate with an encoder using SPI. I get back a 16-bit value every ms (the process runs at 1kHz). However, I now need to transfer the acquired data over ethernet (it has to be ethernet, not UART or anot...
Hardware SetupI am using an ESP32S3 as an I2C master and an STM32G0 as an I2C slave. The STM32G0 is performing two tasks:I2C Slave Communication – Receiving periodic requests (every second) from the ESP32S3 to read dimmer register updates.AC Fan Cont...
