Discuss STM8 microcontrollers, including SWIM, USART configurations, RTC usage, ADC issues, and debugging.
Posted on November 11, 2013 at 16:19I've read the AN2867, and calculated that for having a gain margin of 5, the recommended crystal should have a max ESR of 50K and 6pF load for a minimal 3uA/V transconductance. This will not allow to use any tiny ...
Posted on November 07, 2013 at 15:42Hi everyone,I'm new to the STM community and those microcontrollers too, I'm learning to use them;)I've configured a communication based on SPI through DMA, everything is working excepting the SCK. I've configured...
Posted on November 07, 2013 at 12:40We use the STM8S003 MCU in one of our products and specifically we use the LINbus communications in slave mode. In the 003 datasheet it says the UART (UART type 1) can actually only support LINbus master mode. Whe...
Posted on November 03, 2013 at 00:51Hello. I've a 24C32 on the good pin of my stm8s, I use the stm8 eval library but i've a sEE_TIMEOUT_UserCallback all the time. Is there a better library ? Thank you
Posted on June 10, 2013 at 16:48Hello everybody,I'm programming a STM8L152C6 on the STM8L-discovery. Wanting to improve the consomption I tri to power down the HSI. For that I use the instruction // Clock source CLK_LSICmd(ENABLE); CLK_SYSCLKSo...
Posted on June 13, 2013 at 13:27I want to use stm8L watch dog in halt/halt-active mode. my system wakes up by RTC.1. when I choice Independent watchdog, a watchdog reset happens when system is in halt/halt-active mode. As you know, the option byte(0...
Posted on October 09, 2013 at 23:02I'm using Cosmic 4.3.6 compiler & have a project with greater then 32k code. I need to checksum the flash at startup and periodically during runtime to satisfy UL60730. My first project (about 12k code size) went...
Posted on October 25, 2013 at 00:18I have an STM8L application that needs to scan several ADC channels on a fixed time basis, so I used the ADC_DMA code from the STM8L standard peripheral examples as a starting point. The timer is set to a 1KHz trig...
Posted on October 10, 2013 at 08:52Hello, I have a simple question: uint32_t temp; temp |= ((uint32_t)1 << 16); without retyping it does not work (although if I add the expression to Watch, it shows expected 1 on 16th bit of temp). Why? I use Cosmi...
Posted on September 11, 2013 at 14:17Hello,I am currently working on STM8L15C6. For my application I need to read the value stored at location VREFINT_FACTORY_CONV. The value at this memory location is 0xFF. We were assuming the value to be somewher...
