  1. Hi, I have done the same thing by connecting the TEST and RESET pins to the header pins and programming it from there. Probably you can put a ground pin beside for convenience too. Take note on the max value the capacitor that is connected to the RESET pin is 2.2nF. For more info, see page 110 and 111 of the datasheet: http://www.ti.com/lit/ds/symlink/msp430fr5969.pdf
  2. Yes, that is how my circuit is wired, without the current limiting resistor. Actually, there are two similar portions of this circuit for my project. One for the buzzer and one for the LCD backlight. The LCD module probably has a small current limiting resistor on it (but I will probably remove it). But for early testing purposes, I am taking a 5mm blue LED and directly slotting into the pads meant for the buzzer. Also, the regulator is set at 3.0V so it should be pretty safe for a blue LED.
  3. Sorry for the mistake. That is correct. Vds is ~0.4V.
  4. Thanks for the schematic. If that is true, then the leakage looks awfully large. Here is the link to the datasheet: http://www.nxp.com/documents/data_sheet/PMV16UN.pdf l should probably swap all the N channel MOSFETs on my board to another model.
  5. I can confirm that the MSP-EXP430F5529LP works. Thanks rick! I have a quick off-topic question which I hope you all don't mind I post here. I have a N channel MOSFET controlling the -ve side of the LED. Gate directly to IO pin. +ve side of LED to 3V. -ve side of LED to drain and source to GND. When IO is high, the LED lights up brightly as expected but when low, it is dim but on. Source of MOSFET reads ~0.4V. Couldn't get it to completely turn off even by shorting gate to GND. What are the possibilities here? Sorry if it is too obvious and thank you in advance.
  6. Thanks all for the inputs! I have only tried CCS 5 and 6. I think I have a MSP-EXP430F5529LP lying around but I can't seem to find it... Thanks for reminding me about the erasing part. Now it sounds weird about CCS attempting to erase the device. I don't have a 5969LP for now. You are probably right...probably will consider it during the next sale. I have seen that document before sometime back but I have been able to program other devices (F2274 and F5172 for example) using the MSP-EXP430G2 launchpad and I admit I have kind of took it for granted that spy-bi-w
  7. Hi All, I am trying to program a standalone MSP430FR5969 via spy-bi-wire. From my understanding, the MSP-EXP430G2 launchpad can program any MSP430 device with spy-bi-wire (please correct me if I am wrong). However, I am getting the message of "Could not find device (or device not supported)". Being frustrated and isolating the project for two weeks, I decided to replace the device (which is really a pity as the soldering quality of the first job is much nicer). I am still getting the same message. I tried another launchpad and same thing happened. Then I got curious and tried using
  8. Did you remember to change the PxDIR registers? Mind posting your test program?
  9. If I am not wrong, the coupon can't be used anymore. Maybe you can ask if they can provide a replacement instead? Edit: Checked. "The coupon code you've entered has expired."
  10. Yep, tried it. Even at level 8, it is still very dim (can't even match the bottom OLED brightness level 0 or 1). Hopefully TI would not tell me that this is a nighttime development kit.
  11. I received my MetaWatch. The top OLED looks dead (barely visible).
  12. It does look like Elprotronic's FET-Pro430 program can do this. http://www.elprotronic.com/download.html Look for "FET-Pro430 Lite Software ( FREE )" With the program opened, it looks like under Setup > Memory Options > Read Address Range, you can define what you want to save. Note: I have not actually tried it. Might be a good idea to wait for someone more knowledgeable to chime in.
  13. I am really hoping they will at least provide schematics. Have been really hoping to make an OLED watch (offline version first). I also read that the bluetooth stack for the CC2560 is not open source?
  14. You got me wondering if this happens to be old stock. I might be wrong but since the analog + digital version seems to be much less popular than the fully digital version, there might be a chance that they have a lot of leftover inventory for the analog version? If that assumption is right, these watches might be manufactured and stored for quite a while and the batteries might be over-discharged (and therefore causing damage to the battery) due to standby power and self-discharge? I had li-ions that are over discharged and then refuse to retain energy when being charged. The voltage may r
