Posted on April 17, 2014 at 02:26 I finally got ADC to work, so I went overboard and enabled 6 adc channels plus the temp, vref and vbat all on ADC1. Problem is when its running my data coming out of dcmi seems to get garbled. I know its...
Posted on December 10, 2013 at 03:19Hello everyone, I wrote a hello world program, which is used eCos, for STM32F4 Cortex-M4 platform. Then, I type the command, which is sudo screen /dev/ttyUSB0 -115200, to see the result in the Ubuntu 12.04. It alw...
Posted on April 18, 2014 at 19:24Hi,You probably already get such discussion.I am currently designing a board based on STM32F103RC6 MCU that I want to supply with Vbat=3V6, VDD1/VDD2/VDD3/VDD4=VDDA= 2V4 but in the data sheet, the Vdd min in the USB ...
Posted on January 11, 2012 at 21:46Using ITM_ReceiveChar (void) I get the error ''undefined reference to `ITM_RxBuffer'''. I am able to successfully use ITM_SendChar() as evidenced by getting the corresponding output on my SWV Console so my proble...
Posted on September 22, 2011 at 11:31I have read the ST app note about crystal oscillators and I am concerned about the drive level. Before reading this app note, I chose the TXC 7M series crystals for its small size and reasonable cost. In the data...
Posted on April 18, 2014 at 02:58I'm trying to generate a reset on a USART receive character match on the F3 Discovery board. If I understand the user manual, I need to set bits 31:24 of USART_CR2 to be the character I want to match. The problem is ...
Posted on April 17, 2014 at 22:50Greetings,I'm working with an stm32f215rg mcu and I'm attempting to redirect stdout/in to uart4. I seem to be getting linking errors when attempting to link all the objects/libs together. The line I use is below:arm-...
Posted on April 16, 2014 at 08:34Hi to all, I have a STM32F437ZI and I connected FMC to SSD1963 but LCD is refreshed slow rahter than FSMC. I previously run the same LCD with STM32F407 and I used the same code. I just all FSMC parts to FMC. Where di...
Posted on April 16, 2014 at 03:34I understand it is used to detect whether a device is connected or pulled out. But I have no idea how. So my questions are as follows: 1,How exactly does that pin work? 2,I can use whatever pin that is five tolerant ...
Posted on April 15, 2014 at 08:14When I was trying to use the official USB host library I came by this func: USB_OTG_BSP_Init And it has some of these components: /* Configure SOF Pin */ GPIO_InitStructure.GPIO_Pin = HOST_OVRCURR_LINE; GPIO_Ini...
