Posted on September 30, 2011 at 00:08I am using an STM32F103ZE but could switch to a different model. I need to have all five UARTs running at the same time to receive data from different peripherals. Originally I was thinking of having 5 ISRs to h...
Posted on September 27, 2011 at 13:26Good morning all, First of all, my project:Measure the voltage, current en temperature with an ADC from the STM32 Value Line Discovery. Sending this data to the computer with UART (RS232). The load on the batter...
Posted on September 29, 2011 at 18:35The data sheet I have says it isn't, and yet it's not an ADC input as all the other non 5V tolerant pins seem to be. Of course I'll believe the datasheet if there's no positive information that it's wrong, but i...
Posted on September 29, 2011 at 13:25Hi, is there any samplecode that shows how the LIS331DLH Mems Accelerometer works with SPI Communication? I'm very stuck on that :( regards Alex #lis331dlh
Posted on September 29, 2011 at 13:30Hi, I'm trying to use the USART from the STM32F103ZE to communicate with my Bluetoothmodul. In Adruino I use the USART like this:void setupBlueToothConnection() { blueToothSerial.begin(38400); delay(1000...
Posted on September 28, 2011 at 18:33hi, dear Frs. now i want use the TIM1 ch1,ch2 to decode rf decoded . which is rf encode is diphase coded. i use the PA8 use rf data stream input pin. rf datarate is 9.6k. now i step steps is as belows:stati...
Posted on September 28, 2011 at 18:09I have got the address of the PHY on my board. The address is 7. Now the STM32 is able to communicate with the PHY. But the collision led is still blinking after the initialization. Here is the register dump:0 ...

Posted on September 27, 2011 at 10:58Hi, I am using STM32 discovery board. I would like to use PORTB4 as GPIO, should i disable JTAG? If I disable JTAG, can i reprogrem the boad ? Thanks.
Posted on September 26, 2011 at 02:43I noticed this in the user manual. It also applies to the ARR and CCRx registers.
