Hi there,
I'm looking at switching from my Arduino to a Maple, but my project requires two shields.
1) Is the WiShield 2.0, which correct me if I'm wrong, but I believe has been ported and is working?
2) Is the Touch Shield Slide. It's an OLED Touch screen shield for Ardunios:

Has anyone attempted to use this? Or is there possibly other display solutions for the Maple?

The level of WiShield support is preliminary. Several example sketches work, but things aren't 100%. Given that AsyncLabs closed down, I'm not sure how much further we'll be developing things. The port is here:

About the TouchShield Slide: Are you using it via their customized Arduino IDE? I tried to find the firmware for it in their Arduino fork's github page, but it seems to be scattered throughout the code base, instead of being a discrete library. Do you have any pointers on this?
Thanks for the response.
Ya kinda frustrating that AsyncLabs shut down. Support (even community based) has all but evaporated. Is there another WiFi solution that works with Maple?
For the TouchShield, I'm not using it yet, haven't purchased it yet, but had done some research and settled on it as my display & input solution for this project. I did notice their custom IDE for uploading content to the display's internal memory, but haven't given it a shot yet. There's gotta be a way to upload to it without the IDE though I would guess. So my main concern would be with the library to communicate with it and hardware compatibility (3.3V vs 5V, ect.) and I thought maybe someone in the community here might have experience with it.
I put an email in to the developer about Maple support, so maybe we'll get some info that way...
Are there any other display solutions that you know of for the Maple?

Hi,
I have a Wifly Shield, based on RN131, connected to a Maple board.
I download the corresponding library from https://github.com/sparkfun/WiFly-Shield
But it fails compiling the WiFly library because there is no "pins_arduino.h" file.
What is the corresponding header file for the Maple?
http://leaflabs.com/docs/arduino-compatibility.html says the Wifi Shield is compatible.
Does anyone managed to run a Maple with Wifly Shield?

I finally sorted it out ...
Note that the following is for the SPI1 port, but can be easily modified to match the SPI2 or SPI3 port if available ...
* In "_spi.h", include the "stdint.h" and remove the "pins_arduino.h"
* In "_spi.c", include headers "_Spi.h", "libmaple.h", "spi.h", "wirish.h"
* In "_spi.c", declare the pins as follow:
void SpiDevice::_initPins() {
pinMode(BOARD_SPI1_MOSI_PIN, OUTPUT_AF_PP);
pinMode(BOARD_SPI1_MISO_PIN, INPUT);
pinMode(BOARD_SPI1_SCK_PIN, OUTPUT_AF_PP);
pinMode(_selectPin, OUTPUT);
deselect();
}
* I create the "OUTPUT_AF_PP" case in "wirish_digital.cpp" and "io.h" like this:
case OUTPUT_AF_PP:
outputMode = GPIO_AF_OUTPUT_PP;
pwm = false;
break;
* In "_spi.c", to initialize (based on spi_init and spi_reconfigure taken from spi.c):
void SpiDevice::_initSpi() {
rcc_clk_enable(SPI1->clk_id);
rcc_reset_dev(SPI1->clk_id);
//Disable
spi_irq_disable(SPI1, SPI_INTERRUPTS_ALL);
spi_peripheral_disable(SPI1);
//Mode hardware (to manually drive the NSS pin with the select/deselect functions)
//SC16IS750 supports 4 Mbit/s maximum SPI clock speed means this can theoretically handle the SPI_BAUD_PCLK_DIV_32 (2.25 MHz) divider ...
//speed = SPI_BAUD_PCLK_DIV_64 = 1.125 MHz
//speed = SPI_BAUD_PCLK_DIV_32 = 2.25 MHz
//speed = SPI_BAUD_PCLK_DIV_16 = 4.5 MHz
SPI1->regs->CR1 = SPI_CR1_SPE | SPI_BAUD_PCLK_DIV_32 | SPI_FRAME_MSB | SPI_DFF_8_BIT | SPI_CR1_MSTR | SPI_MODE_0;
SPI1->regs->CR2 = SPI_CR2_SSOE;
//enable
spi_peripheral_enable(SPI1);
//clear registers by reading them
int clr = 0;
clr = SPI1->regs->SR;
clr = SPI1->regs->DR;
clr = SPI1->regs->CR1;
clr = SPI1->regs->CR2;
//flush
select();
while((SPI1->regs->SR & SPI_SR_BSY) == SPI_SR_BSY);
deselect();
}
* In "_spi.c", the transfer function became:
byte SpiDevice::transfer(volatile byte data) {
// Start the transmission
SPI1->regs->DR = data;
// Wait for the end of the transmission
while((SPI1->regs->SR & SPI_SR_TXE) != SPI_SR_TXE);
// Wait for the end of the reception
while((SPI1->regs->SR & SPI_SR_RXNE) != SPI_SR_RXNE);
// Return the received byte
return (SPI1->regs->DR);
}
* i also had to rename the "ring_buffer" variable in parsedstream because it conflict with a maple variable.
* if debugging is activated (i.e ERROR_LEVEL > 0 in debug.h), think about replacing "serial.print" by "SerialUSB.print")

You should have no issue getting the TouchShield to work.
It only uses D2 and D3 for software serial communication. Otherwise, the TouchShield is an Arduino on its own with an LCD and its own IDE. You create the Maple and TouchShield sketches separately. Use serial to communicate between the two. Here's an article on it:

I am also looking for a way to modify the wiFly lib for Maple.
The lib Natalie is refering to must have been updated. Or maybe an older version of the lib was used (if so, wich one?).
Anyone has a workaround he can post for everyone to know?

I try to make it work right now…haven't tested it much but the basic is working…(still lot of nasty Debug and so on… no cleanup at all)
you can find it here:

Check Library/WiFlySerial it's from this side:http://cairohackerspace.blogspot.de/
