I need to use this module in a project. It already comes with a ds 1307 watch and a sd card. The watch I am using the ds1307 component of the flowcode. And how do I write data to the card if the communication with it is I2C? I am attaching a link so you can understand how it works. https://www.youtu...

Hello Kersing;

Sorry, we're over the weekend. Make the most of it.
I didn't even realize it, it was my excitement.
I made a little code. Would it be more or less like this?
See you on Monday.

Thankful;

Ricardo.

Hello kersing;
grateful for the attention.

Can you give me an example in flowcode?

I'm working with the dspic33ep512mu 810 and a 48 mhz crystal. I need a timer with a frequency of 1 hz. Due to the timer properties in the flowcode, the frequency of at least 1,431 hz ((Fosc / 2) (1: 256) (65536)) can be done. What trick can I do to achieve the timer frequency of 1 hz, without changi...

Hello Benj; Seizing the occasion. There is an old project that was stopped and I went back to work. As I formatted the computer it is giving an error at the time of compilation presenting the following message "sor 'is out of range. Suggest large-code model". large-code and explain where I put it. I...

Hello Benj; Grateful for the answer. The error resolved. I had the iobit malware fighter installed on my computer. It looks like it was causing the problem. It solved without it. Could that be it?

Hello Benj thanks;

Understand.
The version I'm using is in English, can't you configure it for Portuguese for example?
I ran a small test program attached below and got this message from the compiler "PIC16 toolchain is not instaled"

Thankful;

I installed FlowcodeV8_Installer.msi and everything was ok. When I install FlowcodeV8.2_Patch.msp and FlowcodeV8.2.2.15_Hotfix.msp I have the following message "the update patch cannot be installed by the windows installer service because the program to be updated may be missing"


Thankful;

Hello benj;

I did the led test and it didn't work.
With this program I gave you was using a crystal of 20mhz and the display worked.
I removed the crystal (there is no external crystal) I changed the settings it gave me and it still does not work.
Can you still help me?

Thankful;
Ricardo

sorry benj this program

sorry this program

Hello Benj;
Thanks for listening.
I changed the settings and ran the program below but it didn't work.
(OBS) I am not using any external crystal.

Thankful;

What is the maximum clock I can with this microcontroller (internal) and how do I set it?

Thankful;
Ricardo.

I would just like an example code to do this

Thankful;

I want to use the 16 bit dac8552. Its serial input is 24 bits 8 commands + 16 data. I would like a sample writing code by sending these 24 bits. Because the first byte is command and the other 16 are data. So the data range from 0 to 65535. My question is also how do I turn this into 2 bytes. Second...

I'm trying to use the ic dac8760. It is a current transmitter and voltage ex (4 to 20 ma, 0 to 5 v) simultaneously. Your communication is SPI. From what I understand each write is 24 bits. Since the first bits msb select the registers and the other 16 bits are the registry settings. Could someone gi...

I am creating a flowchart, however this is becoming quite large (5.8k). My processor is a dspicep512mu810.
By the time I was compiling everything ok.
But now I add a macro and it compiles with error.
Can someone help me.
The compiler error message is attached.
Thankful;

LeighM Hello;

Sorry for the delay in answering.
I've been looking at the data sheet.
The memory is an EEPROM 512KBIT 1MHZ ON SEMICONDUCTOR.
I bought 2 units in the digikey and in both the same thing happens.

Thankful.

I'm using an i2c 1mhz memory. My microcontroller is a dspic33ep512mu810. My i2c is channel 2. I am using 2 macros available in the forum I will attach (i2c send, i2c receive). I have data loss at this speed. The i2c channel only works by software and hardware not. In the macro i2c transmits I had to...

I am using the ds3231 component.
I need to calculate in seconds the final value between a starting date and time / and a date and ending time.
Could someone give me an idea how to do it?

Thankful;

Ricardo.

Hi Martin,QMESAR; All right? I changed the MCU by one by one 33fj256gp710 that when I open the properties panel there are 2 channels uart hardware, and I used one of the channels. It worked. I showed in the display 62 decimal> ascii and 13 decimal CR ascii. But I have to use the MCU 33ep512mu810. Wh...
