Configure Timer in EasyMx PRO v7 for STM32 + Looking ahead

[BenOve]

The valves have the priority for now viewtopic.php?f=180&t=69819
but it would be very valuable to look ahead and find right approach

The main job is to control the (up to) 16 valves
and at the same time collect info as fast as possible during one revolution
and then send that info over UART during next several revolutions,
It should be several hundred such yellow blocks.

If it is possible to capture 1024 such yellow blocks during one revolution
it would be 1024 blocks * 32 bits * 6 rows = 196 608 bits = 24 576 bytes
Can the 64 KB SRAM in STM32F107VCT6 be used here ?
Should the faster chip STM32F746-100 be used instead ?

When UART job is done - start new collection from degree=0

ttttttttttttttttdddddddddddddddd = 16 bit time from reset + 16 bit Crankshaft Degree from Reset point
vvvvvvvvvvvvvvvv=16 bit valve pattern Could look like 0001000100001100

Does this seem possible to do ?

Thanks for help and comments regarding
initiating two timers and writing the code !

Hi,

What you are trying to do is possible.
Similar thing has been done on cars for many years.
In my opinion this can be done with a 8 bit micro controller to run reliably.
