how to configure flex pwm to give complementary pwm of 20 khz.

[kjay]

.i need help with calculating clock and time peroid and waht is other pwm pin if pwm0 has d10 which is complemetary pin in spc56el70l5-disp

i happy that you went to great deal helping me...thank you. i have another doubt..i received extended CAN that has been sent by my CAN hardware PEAK CAN...i received using ID mask 0x70...it receives and blinks LED as indication...i need help separating that received data alone to a variable so that i can use in my functions...i need support on this ...i attach my main file...

Hi,

if you receive the correct CAN package with the expected ID, you should find the received data in crfp.data32[0] and crfp.data32[1].

i got wrong values is it data type mismatch

[kjay]

posted a file.i send this via CAN

[kjay]

my program and datatype is uint32_t for recieving variable

Hi,

if I have understood, from the picture test2.jpg it seems that you are transmitting 00 00 00 44 - 55 66 77 88, and from the picture testcan1.jpg it seems that you are receiving 68d = 0x00000044 - 1432778632d = 0x55667788. So, it seems that the transmission works fine. What is the issue?

Best Regards,

hi zambrano.luigi,

i need to configure another channel to produce same 20khz complementary pwm...that is 2 complemetary outputs, 4 pwm pins...i tried and first 2 only working ...what am i missing ...i tried configuring pwm1 also ..i couldnt find pins for that..help me i attach my application

Hi,

you have to configure the output pins on which the new complementary PWM signals are output. For example, you can use the pin C[15] for the FlexPWM0 A1 and D[0] for the FlexPWM0 B1 (see A1_B1.jpg in attachment). In this way the new 2 complementary PWM signals will be output on the pin D9 and D10 of the connector X6 on the SPC56xL Discovery board.

cannot edit io setting on configuration.xml

thanks for the help...i already configured in pin map editor isnt that enough ...or i should configure in a way you stated...
