L293D 11 Posted December 12, 2012 Share Posted December 12, 2012 I don't have one of these yet, I am still waiting for mine to arrive. My question is this: How many "individual" pins on this board are capable of doing analogWrite? I say individual as on the MSP430G2553 while there are 6 pins available, certain pins share the same timer, so you can only use 1 pin out of a "pair" which share a timer. So, that said, does anyone have an answer to this? Thank you! Also, I read somewhere that the pins on this board are 5 volt tolerant, however while reading the datasheet, it looks like that isn't the case. Would be great if I could use this board with 5v logic (even if it is being powered by 3.3v). Can anybody weigh in on that? Quote Link to post Share on other sites
energia 485 Posted December 13, 2012 Share Posted December 13, 2012 All the PWM's can operate simultaneously. You can find the pins that support PWM (analogWrite) in the pin mapping on: https://github.com/energia/Energia/wiki/Hardware If you would like to know on what timers are on what pins then you can find that in hardware/lm4f/variants/stellarpad/pins_energia.h 5Volt tolerance: From the data sheet section 10.1 Signal description: "All GPIO signals are 5-V tolerant when configured as inputs except for PB0 and PB1, which are limited to 3.6 V" http://www.ti.com/product/lm4f120h5qr L293D 1 Quote Link to post Share on other sites
L293D 11 Posted December 13, 2012 Author Share Posted December 13, 2012 Thank you very much. I am sorry that I missed the reference in the datasheet. Quote Link to post Share on other sites
