STM32F051R8T6 as Modbus rtu Master with RS-485
Hi,I am using Stm32f0 as the modbus rtu MASTER, I have done setting up UART1 Rx and Tx for communication, I am sending the Master query to the Slave device (Simply Modbus Slave application) link https://www.simplymodbus.ca/download.htm. If I connect ...
Configuring STM32U575 for I2C DMA transfer
I am working through a workshop tutorial on how to configure and use GPDMA transfers via the linked list functionality provided in STM32CUBEMX. When setting the linked list runtime configuration a Source Address, Destination Address and Data size are...
Resolved! ST4485EB : is it 5V compatible
Hi,The ST4485EB IC mentions that it needs a 3v3 supply. How can we ensure that the A and B lines interoperate with other RS485 devices working at a 5V logic level as the datasheet mentions . Should I just provide 5V supply to this chip so that it int...

Resolved! How are the BLE attribute handle offsets defined?
Where can I find documentation on the BLE attribute handle offsets? I was adapting code from the sensor demo for the BLE NRG 2 and am trying to understand the "aci_gatt_attribute_modified_event" callback. Through observation and experimentation I fou...
Issue with I2C Communication between STM32 Nucleo-F429ZI and Raspberry Pi 4
Hello everyone,I am currently working on a project where we are trying to send random data from an STM32 Nucleo-F429ZI to a Raspberry Pi 4 over the I2C interface. We have encountered an issue where the I2C address is not detected on the Raspberry Pi ...
Resolved! STUSB4500L Logic Voltage
I am wondering what the logic voltage is for the I/O pins on the STUSB4500L. Under operating conditions they are listed as 0V to 4.5V, but the example circuit shows I2C pullup resistors to 3.3V. Is it safe to connect these I/O pins directly to a 3.3V...
