Re: EB024 / Bluetooth component buffer size
Customisation applies only to individual projects. Any changes that are likely to be a common requirement can be made to the corresponding component C file in the Components folder of the Flowcode installation. The changes would then affect every program using the component (save a backup of the ori...

Re: EB024 / Bluetooth component buffer size
Hello Robin, The size of the Bluetooth string buffer is set to a default value of 32 bytes. The buffer size can be adjusted from Flowcode by using the 'Custom Code' feature. With the Bluetooth component selected in the Properties panel, click on the dots next to 'Custom Code'. Select [Defines] and c...

Re: Flowcode for dsPIC/PIC24 'best chip'
The 40-pin socket of the EB064 is compatible with two devices from the current 16-bit PIC range: the dsPIC30F3014 and dsPIC30F4013. The 3014 can be considered to be a good general purpose device (5V operation, maximum number of port pins available in this format); the 4013 is similar but with more m...

Re: Problem with EB063
Hello Andreas, The connection jumper links on the E-blocks are used to provide default connections that are useful for most devices. In the case of the EB-063 the connections selected with the jumper in the B position are based on the hardware SPI connections of the PIC16F877A on Port C (used if Har...

Re: quadrature encoders pic18f2331
The encoder module can be configured to generate an interrupt when an over/under-flow occurs. Alternatively, the count value can be polled regularly so that over/under-flow events can be detected in software. In either case, the events can be used to increment/decrement an additional counter (e.g. a...

Re: quadrature encoders pic18f2331
The MAXCOUNT value demonstrates a feature of the encoder module that allows the position to overflow back to zero at values other than the 65535 limit of the main counter. This value is also loaded into the main counter if it underflows (running backwards) instead of 65535. The value can be used to ...

The terminals provide direct access to the relay contanct, which have no internal protection, so must be supplied from a suitably protected and fused source. Any work ...

Re: Need help with rs232 & LCD board
Another possible problem, if you have configured the device to use the external crystal oscillator, is that the EB019 is supplied with a 20MHz crystal and you appear to be using a 16MHz device.
You might need to change the crystal to allow it to be used by a 16MHz spec device.
