Hey I am using a STM32L486Z6Tx as an SPI slave, the device transfers blocks of 3588 bytes (512*7 + 4 byte checksum). At spi clock rates up to 1.2MHz everything works as planned. However at higher clockrates I still receive all my data, the checksum p...
Hi every one; using a STM32-F401RE board , how can i canghe on the fly the period and duty cycle of the two signal got in complementary PWM death time using ARR and CCR register?
Hello guys,I have just started working with stm32 controllers. I am trying to capture the frequency of signal using timer 2 input capture mode.I am getting absolutely correct frequency if i use ARR = 65535 but when i use ARR = 0xffffffff (As timer 2 ...
Hello,I've experience in using IDEs to create and run a projects in windows platform. But I've no experience in ubuntu.Now I need to work with STM32F4 mcu in ubuntu platform without using any IDEs (I can use editors). So how do I get start with this?...

These are obviously leftovers from text which was in description of whatever mcu famiy the original source of this timer was (ST9 family?).This of course goes across all timer chapters within this RM, and across several RMs.JW
I need to count over 1G with a 16-bit timer, measurement accuracy is very important to me. I had to do it using a single timer, do you have any suggestions? I am using stm32f0 ant timer1Thank you
Hello, We are interested in developing a product with this MCU but we are not sure when it will be available. Can you help me with some information? We are really early in the dev. cycle and we are not going to "mass produce"(hundreds of units or tho...
