Posted on August 06, 2011 at 00:00I'm using the STM32F103RCT6. I need two PWM outputs, where the period and polarity of each is the same, but one output is 180� out of phase from the other. A duty cycle change must affect both concurrently. The c...
Posted on August 12, 2011 at 12:18Hello,I'm trying to figure out the production process of my product and I cannot understand how the SYSCFG_MEMRMP bits work.Is it possible (and how) to put the boot pins physically (via pu/pd res) to boot the builti...

Posted on August 12, 2011 at 12:19Hello everybody. I would like to ask about measurement of Vrefint using ADC1 in STM32F106 64 pin. After conversion I get 0x18E. How to convert this value in voltage? #adc1-stm32
Posted on August 02, 2011 at 15:52I use DMA to write a string to USART2. After power up I trigger transmittion by pressing down a switch and detect ( oscilloscope ) that the usart transmitted two bytes less than expected - after that every time I t...
Posted on August 11, 2011 at 16:58I'm trying to comunicate with SD card with STM32F100RB controller via SPI.I am able to erase blocks on card, and to read them. The problem is about writing blocks to card. I am able to write something to card, and ...
Posted on August 10, 2011 at 22:55How much is there, really? And how much is really available? The specs all say 16 mbit, but the part and the schematic show 32 mbit, or 4 MBytes. Looking into the code examples include with IAR EWARM, it seems on...
Posted on August 10, 2011 at 17:15Hi STM32 users, I need a serial terminal able to 1. Send file using ymodem file transfer protocol 2. Send hex (not ascii) text format I was using hyperterminal but it can't send hex format. I have found hercules but...
