STM32 MCUs Products

We are developing PLC using STM32F429 CPU. It will have Ethernet,CAN,RS485 port and Multiple ethernet protocols like-TCP/IP,ModubsTCP,MQTT,OPCUA .Please guide is this cpu is a right choice.? We want low cost controller.

Not able to read data from STM32G031 Mcu I2C slave

I have configured my stm32g031 mcu as an i2c slave. My PC terminal is my master device and is connected to mcu via FTDI cable. When I do a i2c write, I can see mcu receives the data. But when I do an i2c read, I can see it reads 255 on my pc terminal...

MCU support both 1.8 V GPIO and 3.3 V GPIO

Hi, I am looking for MCU which support 1.8 V GPIO and 3.3 V GPIO,My target is about 20 pin 1.8 V GPIO and about 10 pin 3.3 GPIO.After my search, I think STM32F0x8 can meet my requirement.I want to know are there STM32 low power series MCU or STM32 Hi...

Is STM32L4Cube v1.16.0 RCC_HSICALIBRATION_DEFAULT set up properly for STM32L432KC?

On STM32L4Cube v1.16.0 the RCC_HSICALIBRATION_DEFAULT is set to 0x40, but was 0x10 with v1.15.1 HAL versions. My UART module is using the HSI, hence I need quite precise frequency and it was alright with v1.15.1 (around 0.1% accurate), but after I h...

STM32G030F6 / STM32G031F6 interoperability

At the moment we are struggling to get hold of any STM32G030F6's but we can get hold of STM32G031F6 chips. I've done an CUBE generation in the same pinout as the STM32G030F6 project and compared between the two projects and it looks to me that as lo...

SOME BUGS to received more than 64 bytes of data on USB CDC ..I used STM32L4 series Controller

When I transmit more than 64 bytes data then its working fine and received upto 64 bytes data its working fine. I read some Documents On internet but not got clearwhen I pass 100 bytes of data from host so its not working.#define USB_HS_MAX_PACKET_SI...

Is possible integrate an st link probe into a custom prototyping board ?

I'm developing a prototyping board  based on STM32 MCU.I want to integrate on the board an st-link probe for easy debug.Is possible integrate an st link probe into a custom prototyping board for example uploading the st-link firmware into an STM...
