Posted on September 26, 2015 at 07:30Hi, My device supports max 500khz SPI clock frequency, So how do i configure my STM32F051R8 to support this frequency. #i2c #crosstalk #stm32f0 #spi #uart
Posted on September 12, 2015 at 15:51I'm using STM32F051R8 board but i'm unable to configure UART in 7bit bata and one bit parity mode. Tried changing M and PCE bits of UART CR1 register but no luck.
Posted on August 14, 2015 at 06:47I want to know how should i connect RE and DE pins to max485 via GPIO pin and how RE and DE pins are mapped to DB9 pin #stm32 #serial #rs485
Posted on September 12, 2015 at 16:14 Tried and not working. The device which is sending data operates on 7 data bits and even parity so I'm unable to receive data. In reference manual on page 698 they have mentioned table please refer it ... I'm u...
Posted on August 18, 2015 at 07:59Thank you all for replying and clearing my doubts. I think i don't need TTL to RS232 and then RS232 to RS485 converter and voltage level converter to control RTS signal. I think all i need is MAX485 IC which i menti...
Posted on August 17, 2015 at 07:43Thanks for replying clive. According to your explanation i should control my transmission depending on one GPIO pin (set for TX and reset for RX). What i have is TTL to RS232 converter and RS232 to RS485 converter t...
Posted on August 14, 2015 at 14:18Thanks for the reply I've gone through the figure but still I'm not getting how i should control RE and DE pin in 485 through one of the GPIO pins on my board.
