Hello,

Three accompanied PWM waveforms

Is there a recommended way of producing three accompanied PWM waveforms on an RA4M1?
Two is easy with the two outputs from one counter, but how about three?

Should I start two counters together, and hope for the best?
Should I set one to count to a higher figure, and also use the second one to reset the first?

Thank You

    Hello @Vikas, Thanks for posting your question online. Yes, one way to have multiple synchronized PWM waveforms is to start multiple counters at the same time, as you can see in the screenshot below Regards, Julian White

Hii, It’s getting as far as setting NEWDATA in MCTL_RX (also sets MGSLOST, presumably when the coming message arrives). It also sets NDST in STR.

An acknowledged pulse is transmitted on CTX. So, I presume the filters are set correctly.

STR isn’t in HALT or RESET. The relevant bit is set in MIER.

is set to 0x4D, but bit 16 (IR) remains clear. The interrupt handler routine is never invoked. ISER0 bit 0 is set.

Other interrupts are working (RTC). Is there some other global interrupt enabled within the CAN module that I’ve overlooked?

RA4M1, SPI with DMA?

Hi, I search for a small example for SPI Master and DMA transfer. So that I can receive e.g. 15 bytes with DMA and get a transfer end to intrude/ message when it’s finished. Thanks in advance!

    Hi , The RA4M1 does not accept external parallel buses.  In order to add external memory to this device, for instance, you would need to use the IIC or SPI interfaces. Thanks
