STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on April 03, 2012 at 06:52I have a project involving STM32F103RE. A timer channel TIM2_CH2 triggers a continuous read on ADC1, which uses DMA1 into a buffer. What I want to do is set up ADC3 to read a different channel in a similar fashion us...
Posted on April 11, 2012 at 19:48Hi, I got two different devices with the microcontroler STM32F103RB which I'm trying to comunicate between them using the SPI protocol. The element A, is the master : The element B, is the slave : When I send from A(...
Posted on April 11, 2012 at 21:40Hi everybody, I'm new in STM32/Cortex M3. Commonly I create an application then write to chip's flash. Now, if I want to create an application stored in SD card then run that application. What the way for MCU do that...
Posted on April 11, 2012 at 18:48Hi everyone,I'm very new to STM32 Discovery and I want to do some project with it. I need to capture PCM signal(voice) from GTM382 modem before it reaches CODEC. I know there is PINS:MCLK - 2MHzPCMSYNC - 8 kHzPCMI -...
Posted on April 11, 2012 at 14:55I need to re enable interrupts in an interrupt service routine so I can do some I2C communication (my I2C driver uses the error and event interrupts). But I'm not clear as whether I should use CPSIE i or CPSIE f to ...
Posted on April 11, 2012 at 16:12Hi, I downloaded the package : LwIP TCP/IP stack demonstration for STM32F4x7 microcontrollers. I tested different programs : udp_serverclient, tftp_server without RTOS and udptcp_echo_server with RTOS. And now I sear...
Posted on April 11, 2012 at 02:22I seem to run into a lot of issues! I'm trying to get my STM32L Discovery board to wake up from low-power sleep with the Flash turned off. I'm using the User button (tied to PA0) to wake it up as an external interrup...
Posted on April 10, 2012 at 17:50Hi,I am a university undergrad and I am designing a Digital storage oscilloscope. I need the micro controller's DAC output for DC voltage. I have seen the sample code and I know how to setup the timer, link the DMA t...
Posted on April 01, 2012 at 23:12in my project, i must generate a sinusoidal wave and i have to receive this wave by ADC. this signal is a response harmonic of a filter. so i want to calculate the gain and the phase shift but i don't know how. can i...
Posted on April 10, 2012 at 12:18hi i'm wondering how can i program the stmf4discovery using the usart??
