is Keil Logic Analyzer thru SWI supported by nRF52832 ?

[leey]

Hi,

I was trying to plot incoming ADC variables using Keil Logic Analyzer function inside the IDE.

So far no success; I am able to use it when using STM32 board.

Is this function supported by nRF52832 ?

Thanks.

I edited you question, because your indentation (tabs) made the forum software think your question was code.

I presume you mean you want to write debug text into Keil, is this correct ?

What STM32 board were you using? BlackMagic Probe ?

Hi,

Keil Logic Analyzer uses Trace to interface with a target MCU. On the nRF52832 there is a Trace Port Interface Unit(TPIU) you can use to connect to an external debugger that supports trace, in order to use Keil Logic Analyzer. Note that debuggers with trace-functionality tend to cost quite a bit more than ones without this feature.

There is also a blog post here about using Trace with the nRF52832 you can read.

Figure showing the TPIU port:

Or buy a $2 USB to serial adaptor and use the UART to log via NRF_LOG_INFO etc ;-)

Yes, for just reading the ADC value NRF_LOG should be enough. But if you need something more advanced, for analyzing e.g. SPI/I2C/UART, a logic analyzer is great tool. But I would then recommend buying a dedicated logical analyzer, e.g. from Saleae Logic.
