Hi Ben

Don’t want to change crystal as potential problems likely with booth loader and other things

May try an 8 meg 3.3v arduino

But really wanted a small mod to the software SPI clock freq


Already use the analyser you mention and that’s fine for just monitoring the lines

Hi

I am using my flow kit 2 to analyse some SPI signals using megga 2560

I have set the slowest clock speed i can currently select on the megga 2560 ie /64

But currently do miss a few clock pulses even if i set the clock speed to the FOSC /64 on the megga

Is there any way i can reduce the SPI ...

Hi

Many thanks for quick response that has now solved that particular problem

Will now continue to next stage to try and read the 4 analogue channels in burst mode

Not sure if will be successful but will try and of course any further hints or advice is always welcome

Out of interest using a ...

Hi

Trying to interface to max22530 a/d converter

Having some problems as need to use in burst mode

ie i want to select register x01 and the unit will send back 16 bits

Tried to use spi master to get byte array to allow storing of the received data

But cannot seem to get the drop down box to ...

Hi

i noticed whilst looking for an i2S component in flowcode there is one but is named I2S master slave ESP32

1. Is it possible to use this with a dspic ie ECIOP16 or is there a separate one for the dspic

2. i also wish to use the i2s in conjunction with the DSP functions is this feasible i ...

Hi Ben

I have already used some of your your DSP functions before using EB085 & EB086 using DSPIC

But now looking at practicality of carrying out some DSP manipulations this time using input from a codec chip using i2s

Need to sample 2 analogue inputs 24bits sampling each around 300khz and ...

Hi Ben

That's great now faster and suitable for my current Project needs

As an aside over next week or so i will also now try the MODUS TCP option using a ESP32 WROOM just to see if any benefits switching from my dspic33 to ESP32

Many thanks again

David

Hi Ben

Thanks for your comments

Have reduced further the receive and timeout properties and a bit better

Also as i said before is it possible to modify the APP event trigger to enter miili seconds rather than seconds as this would be better

Although do not reaaly want to but if i were to ...

Hi Steve

Enclosed is a simple APP program for illustrating the point i was raising

The program scans 11 registers from Modbus slave 1 ( also updates the slave register 6 to test the writing)

This all works fine when connected to an ECIO40P16 running Modbus RTU at 115200 Baud

The issue i have ...

Hi

From experimenting with the APP developer it looks like the fastest update time is just less than .4 seconds

This appears to roughly tie in with the APP event trigger available which has a minimum setting value of 1 second

Is it possible to get the APP developer update rate speed up a bit ie ...
