Hello. I try to build 3Hz...300Hz bandpass FIR and see that it requires not less than 63 taps. As I have to use it on STM32 calculations might take more time than I plan. Is it "a law of nature" and no trick would simplify filtering out 3Hz on 1kHz sampling frequency? Thanks Alex. --------------------------------------- Posted through http://www.EmbeddedRelated.com

Hello, I've got an STM32F103Z part and I'm trying to generate a PWM output between 10Hz and 20Hz from the timer 1 peripheral. Depending on how I set the timer 1 prescale value (timer 1 is on the 72Mhz high-speed bus), I get more or less accurate output results which can vary by up to 1Hz from the target frequency. The only thing I can think of is that the external oscillator (8Mhz) is off...

Hi, I'm trying to access to two SDIO card on the same bus with my STM32 but only one at the time is answering. I am doing the same things said on this thread without result: http://www.youtube.com/watch?v=3p-XqvMOTYA I am receiving a CMD_RSP_TIMEOUT the second time I send a ALL_SEND_CID meaning that the first sd card is now in idle mode. Is there any register of the sdio port I shoul...

Greetings, I've been playing with STM32F103RE and DS18B20 1-Wire Digital Thermometer. Judging from what I have seen (examples regarding I2C and *duino projects regarding I2C), it requires somewhat different approach due to the "reset" part in its initialization. Can someone provide code for connecting that device to STM32 uC's (I'm using STM C libs and uVision 4), as I am perplexed w...

http://microcontroller.com/news/STM32_F-2.asp The STM32 F-2 runs out of Flash at 120MHz. Has two USB 2.0B OTG ports, Ethernet, 528 bytes OTP memory (who remembers what OTP means?) and plenty of peripherals. The STM32 F-2 is from STMicroelectronics http://microcontroller.com/STMicroelectronics.htm Article contains a block diagram and a family roadmap. Bill Giovino http://Microcontr...
