STM8S UART Receive problem

Posted on August 02, 2016 at 13:24I have a weird condition in which the STM8S003 does not read the entire packet I'm sending using a PC serial port. For example I have sent 256 bytes using a PC software but at the end I have only read 214 bytes inst...

GNNS1A1 Serial Issues.

Hi,I am currently attempting to create a development board stack up starting with a Nucleo-f401re, GNSS1A1, IKS01A2, and SX1276MB1LAS LoRa shield in the order listed. I was having difficulties getting two stack ups to communicate through radio and r...

Hi, I am using STM8L, and I want to program multiple STM8L MCUs using SWIM so is it possible to program the same? What hardware connection will be required for it?

Receiving Galileo frames ?

HelloAll examples available in CubeMX reguarding GNSS1A1 shield are using GPGGA frames, which, if I am right, are emitted by GPS satellites.I am interested with GAGGA frames from Galileo satellites, which are supposed to give better accuracy. Can yo...

what's the application scenario of the CPUDIV in CLK?

We can get the information that the CPUDIV can be used to divide fMATESR for CPU. And the divide ration can up to 128：1. I wonder that when you configure CPUDIV to 128:1, can CPU works normally when access peripherals such as I2C. Or CPUDIV is just ...

Hello, I am trying to initialize I2C, but getting continuously high signal on both SDA and SCL pins . Can anyone suggest what can be the issue?

STM8L151 - can't get a PWM signal

Hi,Does ST have some code samples to use PWM on STM8L151 ??If so, where can I find it?Thanks,Itai

i set timer1 channel1 registers as the same as timer1 channel 2,3,4 but it does'nt work
