Hello All I was out at the customer this week and installed flowcode onto the laptop with a program I did from the office desktop. I then got compiling errors, and to get rid of them I had to cut back the code by a very large proportion. So much so that I could only demponstrate the bare basic's of ...

Thank you QMesar

I have done what I can with attempting to vary the perieods and frequencies with no luck. I think what I will try next is use the high speed PWM peripherals on the dsPIC33EP32MC504 with C (rather than the PWM component) to see if the issue persists.

Thanks

Hello All I am trying to use the PWM outputs form the dsPIC33EP32MC504 to gernerate various waves from data stored in a LUT. In general it works very well, however I seem to be getting glitches on the falling edges (aways seems to be on falling, and never rising). As you can see in the triangle wave...

Hi All We have a job opening for an experienced flowcode programmer. if you think you are up for the position, please can you PM me with a CV? Thanks Embedded software engineer The Experienced embedded engineer will be required to take control and responsibility for various projects from concept rig...

Hi Ben I am modifying this with more boards, and it seems like every Gygo has a different steady state. This was previously OK, but some of these new ones coming in have very high stationary values (above 15000). Is there some way I can easily set the default to 0, or do I need to do this in code to...

Hi Leigh

The probelm is we cant disable the re-mapping of the pins. On the software mode re-mapping is always on, and the pins available for the remapping are not the standard hardware pins.

Thanks

Hi All We are trying to use the MCP4261 in a design, however when we add the component the parameters try to re-map to different pins as default. We dont need to re-map the pins and want to use the default pinout (MOSI D4, MISO D5 and CLK D6). There are no options to select these pins, even if we at...

Morning Ben

Is it possible you can look into my previous post with the ADC's and the thermistors? It is not a noise issue as all the ADC inputs (including thermistors) have a 0.1uF cap to GND near the ADC pins.

Thanks

Hi Ben I have another "Qiurk" with the Q10... I am running on the inteernal 64Mhz oscillator, and one some chips the ADC works fine, but on others I get some random values. I have managed to get around this issue on some of the ADC's by decreasing the conversion speed (to Fosc/64). This st...

Hi Ben I think I may have found another issue with the Q10... As soon as I add the EEPROM component onto the panel then try and compile I get the following compiling errors. -w=359,1273,1388 -fshort-float -fshort-double -std=c90 -Os C:\ProgramData\MatrixTSL\FlowcodeV8\CAL\PIC\PIC_CAL_EEPROM.c:212:18...

I found the issue with this

Hi Ben

Any luck with this? I just need an example of how I can extract say the z-axis data.

Thanks

Thanks Ben I will do some tests to see which component is the culprit. I have attached the latest testing variant of the Gyro test (still in software). When running I seem to be getting some data on Data2, but nothing on Data0 or Data1. Do you think you can take a look and let me know how I can dist...

Hi Ben Thanks for the reply. If I disable the SPI component compelty, and then try run in hardware the program freezes (the OLED backlight comes on, but shows blank screen). I can get data if I run in software mode. I have attached my program for you to see. I also seem to be having reading the data...

Hi Ben I have the SPI MAster connected to the same pins as the SPI Gyro (MOSI, MISO, CLK) but with different SS for another component. The program compiles fine, but when I test it on hardware the it freezes. When I then set the Gyro to software mode it does not freeze. Is it possible to use the sam...

Thanks Ben

All seems to be working fine so far...

Hi Ben I have copied the file in into the the stated folder, re-started flowcode and even cleared the cache. I have tried multiple channels of the PWM, saved the program under a differnet version number, re-compiled but unfotuantly it still does not seem to be working. Do you think maybe its got som...

Thanks Ben

Hi Ben

I have tested the "#define MX_TIMERSELECT0"

Unfortuntalty I still dont get anything when compiling on any of the PWM channels.

I measured all the pins just to be sure

UART still works fine

Thanks

Hi Stefan I am fairly sure the dsPIC33EP32MC204 device does have two hardware I2C channels. I only need one channel (channel 2) using B5 & B6. I can not change these pins as the design is on a PCB. The 24C32 works perfectly when I use software B5 and B6, but as soon as I switch to the hardware o...

Hi All

I am using the dsPIC33EP32MC204 with a external EEPROM 24C32.

The 24C32 works perfectaly when I use software mode, but I get no I2C when I use hardware mode channel 2 (SDA on B5 and SCL on B6).

Can anyone help with a fix?

Thanks

Morning Ben

Do you think you might have a chance to take a look at this today? The new assembled PCB's should be arriving any minute now and it would be good if I can complete the project this week.

Thanks

Hi Leigh

Yes, it does work. However I still needed to add a 200us delay before re-setting the time and sending the data packet. Still better than software though...

Is it possible to edit the UART hardware component to add this option rather than using the timer?

Thanks

Yeah, I can see that working...

The timer will need to be different every time as I have a different number of data packets, but definitely worth giving a go.

Thanks Leigh

Hi Guys I have now moved on in the project to get the RS485 working. Issue I am having is I would like to keep the UART based in hardware rather than software. As the RS485 IC's use a NOT RE and a DE. I tie these two pins together and just use them as a single write enable pin (I have attached the d...
