Posted on August 22, 2013 at 18:12I'm new to ARM and have been doing a lot of work/research on DMA on the STM32F4 Discovery board. I have multiple DMA streams working correctly for SPI to an OLED and some LED controllers but I have a fundamental qu...
Posted on August 22, 2013 at 12:05I have chose the STM32F405RG and the st-link debugger.The program is used for STM32F407-DISCOVERY at first.It can work at the STM32F407-DICOVERY,but after I changed the device and other options.
Posted on August 22, 2013 at 21:40Hello guys,Im new to the ST-Family and i have a question about interrupting with a button.I wanted to make the button on the board as a hardware interrupt, which would trigger some LED-Blinking.However doesnt work a...
Posted on August 21, 2013 at 17:07Could anyone kindly through me a working example for the temperature sensor. I have build one on my own but have no way to verify it (use a glass of ice water?). So I'd like to see how someone else wrote the code. T...

Posted on August 22, 2013 at 09:54Hi all, I am using a STM32F103C8 as a master in a SPI communication to an external ADS. My project has other interrupt sources, so I am not using additional interrupts for this SPI communication.The communication d...
Posted on August 15, 2013 at 21:45Hi,We are developing a product using a STM32F051 and want to be able to upgrade the code using IAP. I've been reading anything I can find, AN4065, the examples, etc. It seems like the general idea is that the micro ...
Posted on August 19, 2013 at 07:48I want read ADC of STM32F303VC then display status on three LED (If ADC>1000 LED red bright,ADC<500 LED green bright and extant LED ogrange bright) programmed code below,but i don't find error.Thanks everyone!#incl...
Posted on August 20, 2013 at 12:11Hi everyone, I'm currently developing a product based on a stm32l100r8 mcu. I'm unable to find a document (akin to pm0062 for stml152) about flash/eeprom programming for this chip. Is this document available somewhe...
